Being an amateur and having never done an “official” USA cycling event - do I need to do anything before registering for the amateur race? I am a bit confused if I need a membership or if that is only for elite/open category? I think the answer is I don’t need anything but just wanted to confirm! https://d31phgno5jnghy.cloudfront.net/gravelnats/documents/2025-Gravel-Eligibility.pdf
